1/2 lb frozen uncooked shrimp, slightly thawed, shelled & deveined
1/2 can water chestnuts, drained
2-4 green onions, thinly sliced (whites & light greens only)
1 egg white
1 Tbsp corn starch
1/4 C soy sauce
Wonton wrappers
Oil

Toss shrimp, water chestnuts and sliced green onions together and either chop by hand very finely (too much work!), or use a food processor or a meat grinder to process into a fine mixture. 

Sprinkle with corn starch and soy sauce, and stir in egg white until ingredients are well blended.

Spoon a little mixture into the centre of a wonton wrapper, and using a little water on your fingertips, fold up the ends to make a closed package. (Get creative! Everyone I know has their own design. Mine's pretty basic -- I just pull the sides up around the filling and give it a twist.)

Prepare a steamer -- I use the steamer basket in our rice cooker, but however you steam will do -- and either oil the surfaces the dumplings will cook on or put down clean lettuce leaves (the traditional method).  Steam for about 8 minutes.

Serve with soy sauce or teriyaki sauce or whatever sauce you like.  Usually makes around 16-18 dumplings for us.
